Description

The utility model relates to transport engineering, in particular to auxiliary vehicle frames for trucks.

The crane manipulator is attached to the vehicle frame through an intermediate frame - a subframe. In addition, the subframe is used to mount the body on the vehicle frame. The subframe distributes the load to the vehicle frame and contains longitudinal beams interconnected by cross members.

Known auxiliary frame for installing a crane on a vehicle (patent EP2085295, published 05.08.2009), consisting of at least two longitudinal struts and at least two transverse elements that can be moved in the longitudinal direction along the longitudinal struts using bolts installed through the holes in the longitudinal posts, while the transverse elements are provided with grooves designed to fix the crane with bolts, and the distance between the holes in the longitudinal posts and the length of the grooves are chosen so that the crane can be fixed anywhere in the longitudinal direction of the longitudinal post.

A known vehicle frame (patent for a utility model of the Russian Federation No. 191843, IPC B62D 21/02, published on 23.08.2019), containing spars connected by several cross members, brackets and connecting elements. The frame is equipped with U-section spars, front and rear subframes, while the subframes contain U-shaped spars with inserted L-section amplifiers, subframe cross members, some of which are U-shaped, and spring suspension brackets, the subframes are fixed to the frame using U-shaped brackets and side cheeks, consisting of side plates and vertical ribs, the front subframe in the front part is fixed to the frame brackets using angles, the upper flanges of the subframe side members are tightened with the lower flanges of the frame side members using bolts, when In this case, the subframe brackets are attached to the front subframe at the front.

Known cargo vehicle (German patent No. 19938545, IPC B60P 1/54, B60P 1/64, published on February 24, 2000), which provides universal use of a swap body together with a loading crane. The vehicle contains a frame with at least two longitudinal beams. A crane is attached to the ends of the longitudinal beams. The swap body can be positioned on the ground using support struts, with the truck frame normally lowering the swap body below the swap body using air suspension. The loading crane can be installed on the rear overhang. If necessary, the swap body can be installed on the opposite side, in which case the loading crane will be located behind the driver's cab. On the underside of the longitudinal beams there are spacer reinforcing profiles. The loader crane is secured with ties.

As the closest analogue, a vehicle subframe was chosen (patent for a utility model of the Russian Federation No. 171001, IPC B62D 21/00, published on 05/17/2017), made in the form of a ladder-type frame structure, consisting of two straight spars connected by cross members, and equipped with reinforcing and supporting elements for fastening removable functional modules, the spars are made of box section, and the cross members connecting them are of circular, rectangular and U-shaped cross-sections, and the cross-pieces of circular cross-section are evenly spaced along the length of the subframe, the cross-members of rectangular cross-section are located in its central part, made elongated are interconnected outside the side members by support cross members, and the U-shaped cross members are located in the front and rear parts of the subframe, two of them located in the front part are interconnected by longitudinal circular elements, the rest of the U-shaped cross members are reinforced with tubular elements and plates , at L-shaped brackets reinforced with stiffening ribs are fixed on the outer side of the side members.

A common disadvantage of the known solutions is the lack of the ability to install different types of removable add-ons.

The technical task of the claimed utility model is the development of a vehicle subframe.

The technical result is a universal design of the vehicle subframe, which allows for rigid fastening of the crane-manipulator installation both behind the vehicle cabin and on the rear overhang, as well as the installation of various removable superstructures.

The technical result is achieved in that the subframe of the vehicle, made in the form of a ladder-type frame structure, contains two box-type spars connected to each other by rectangular cross-sections, while cheeks with mounting holes are welded to the outer side surfaces of the spars in the front and rear parts, and plates with brackets and two beams with two container fittings at the ends for installation of removable superstructures on the subframe are installed between the side members.

The claimed solution is illustrated by the following drawings:

Fig. 2 is a side view of a subframe of a vehicle;

Fig. 3 is a view of the D-D subframe of the vehicle;

Fig. 4 is a view B of a subframe of a vehicle;

Fig. 5a is a diagram of the installation of the CMU behind the car cab;

Fig. 5b is a diagram of the installation of the CMU on the rear overhang of the vehicle.

The subframe of the vehicle is made in the form of a ladder-type welded frame structure and contains two box-type spars 1, made in the form of elongated elements and interconnected by cross-members 2 of rectangular cross-section. Cross members 2 are placed evenly along the entire length of the subframe and are connected to the side members 1 by welding. The front ends of the side members 1 widen towards the vehicle cab (Fig. 1).

Plugs 3,4 are welded to the end surfaces of the side members 1 to protect the internal cavities of the side members 1 from contamination (Fig. 1).

In the front and rear parts, two cheeks 5,6 are welded to the outer side surfaces of the side members 1, each with mounting holes of different diameters made in them (Figure 2).

Cheeks 5,6 are steel sheets with a thickness of 6-8 mm and are designed to install the subframe on the vehicle frame, as well as to secure the crane. Cheeks 5,6 are fixed at the same level with the upper surface of the side members 1 and protrude below the lower surface of the side members.

Two transverse beams 7 using gussets 8 (Fig. 3) are welded to the cheeks 5,6. At the ends of the cross beams 7 there are container fittings 9.

Between the side members 1, there are two plates for connectors 10 (Fig. 4), which are bolted. L-shaped brackets for connectors 11, with holes made in them, are welded to the plates 10. Plates for connectors 10 and brackets 11 are designed for mounting hydraulic hoses of the KMU with quick-release couplings. Hoses (2 pcs) are laid in the middle of the subframe between the plates for connectors 10. At the ends of the hoses, quick-detachable connections are mounted, which serve to supply the working fluid when moving the CMU behind the cab or to the rear overhang.

For the manufacture of the subframe, 09G2S steel is used, which has high strength and good weldability.

The subframe of the vehicle is designed to accommodate the crane-manipulator installation both behind the driver's cab (Fig. 5a) and on the rear overhang (Fig. 5b) by displacing the side platform. To move the side platform, it is necessary to disconnect the fitting connections, move the side platform with a manipulator crane and secure it with fittings.

The inventive subframe design allows to evenly distribute the load from the weight of the CMU, the platform and the weight of the transported cargo on the chassis frame, and also increases the torsional rigidity of the subframe structure in the front and rear parts at the CMU installation sites.

The inventive subframe of the vehicle is characterized by high indicators of strength and reliability, and also allows to achieve the versatility of mounting the CMU. The presence of container fittings for fastening the container allows you to install any kind of removable superstructures: tank containers, a body-van for various needs, a thermal box for transporting goods and similar containers.
